GAS WATER HEATER.

Application filed August 21, 1922. Serial No. 583,429.

To(171tclzomitmnyconcerm Be it known that I, Isaac Gonnoi', a citizen oft-he United States. and a resident of Schenectady. in the county of Schenectady and State of New fork, have invented certainnew and useful Improvements in Gzfs \Vater Heaters, of which the following is a full. clear, and exact description.

The invention relates to a gas water heater which is adapted to be operated in conjunction with a single, doub'e or other gas burner in any type of gas range, gas cooker, gas and coal combination range, or gas heater.

' One of the objects of the invention is to provide adevice of this character which will provide hot Water while theburner is being used for cooking or baking purposes, thereby not only adding to the usefulness of the range, etc., andfsaving the space and expense of-a'separate water heater, but also greatly reducingthekconsumption of gas. 1

Another object ofthe invention is to provide a water-heater-of this character so constructed that it in no way 'intereferes with the direct application oftheburner heat to the cooking vessel; but, on the contrary, the'construction of the water heater is such that it"r'eally assists in applying the heat; to the cooking vessel and reduces the loss of'heat by radiation.

Further objects and advantages of the invention will befapparent from the follow ing detailed description when taken in connectlon with the- 'accompany1ng drawings, in wh ch:

Figure 2 is a vertical sectional view of the water heater and burner.

Figure 3 is a plan view of a range with the water heater applied thereto.'

Figure 4 is a rear elevation of a. range and showing the connections between the water heater and tank.-

Figure 5 1s a perspective view of a modi- -fied form of the water heater.

Referring to' the drawings more in detail.

' numeral l indicates a double gas burner con'iposed of two circular pipes 2 and 3, the upper. pipe being. preferably provided with holes arranged to direct the gas horizontally or at to the horizontal, while the lower.

' pipe is preferably provided with holes arranged to direct the gas vertically or at .45 tothe horizontal. The arms supporting the I uppercircular pipe are also provided with associated with the circu holes arranged in the top thereof, as clearly shown. in the drawings. The burner. may

besti'pplied by a single gas pipe, but I pre-- fer to employ separate gas pipes, and I have, therefore, illustrated the gas supply pipe i gas supply pipe 5 associated with burner 3;

t being unt erstood, of course, that, an inde-.

pendent valve is employed for each-supply pipe. i

ar burner 2 and -The water heater. in'thepreferred embodiment. of the invention, is a. hollow, annular, one-piece member 6, having appropriate connections, to be hereinafter described, for the circulation of water. \Vhile I have shown the walls of the water heater as vertical, it will be understood that the innernvall may be inclined. if so desired. It is also to be noted that, insteadof being annular, the water heater may be of any desired shape; for instance, it may be oval or rectangular, etc. burner and the water heater isclearly illus- .trated in Figs. 1 and 2; the arrangement being such that the water heater is almost direct- The relative arrangement between the ly over the lower circular burner, while the i.

ripper circular burner is within the water heater. The water heater may be mounted i in place on the gas stove, gas heater, 'etc., in any des1red.n1anner-, but I have illustrated hangers or brackets 7 which are attached to the under side of the top of the gas range, as shown'in Fig. 3. The position; of the heater with respect to a range is also shown in W dotted lines in Fig. 4.

Figure 1 is a perspective view of the water heater and burner detached from the range.

It may. be noted here that the invention is not limited to use with any particulartype of.burner and its use is contemplated with any type of burner; as, for example, the star burner indicated by numeral 8 .in Fig. 3.

The means for circulating the water is best illustrated in Fig. 4. The pipe 9 sup:

plies water to the tank 10, and the water is carried from the bottom of the tank to the water heater by the pipell. while the pipe portion of the water heater, while the hot water pipe .12 connects with the upper portion thereof. thus assuring a proper circu- 1 0 place of the water heater described lation of the water.

above I may prefer to employ'a coil water i 4 heater 13, illustrated in Fig. 5. The arrangement of the coil water theater, with respect to the burner, is the same as in the ring member 6, and any -detailed illustration or description is believed to be unnec-o essary.

' In operation with a range, the burner is lighted, and a cooking utensil is placed on the range in theusual manner. Ordinarily itwill only be necessary to employ the upper circular pipe 2, and the flames from this burner-striking against the wall of the water heater .will rapidly heat up sufliz-ient -water forordinary purposes; and at the same time the water. heater acts as a hood or heat concentrator to confine the heat within the spacedefined by its wall and cause it to be applied to the cooking vessel.

, It is thus apparent that by the use of my invention there is a great savingjn space and expense by eluninatin the separate Water heater; and, further, t at the relative arrangement between the burner and water heater is such that all of the heat developed is employed for a useful purpose, thereby eliminating to a large extent the heavy loss .of heat which in pr1or constructions merely raised. the temperature of the surrounding atmosphere.

, In the event that an unusual amount of hot water is required, it is only necessary to light the lower burner, which is'so located that, the heat therefrom is'applied almost directly to the bottom of the water heater.

Where my water heater is employed with agas heater or other device, except a range, the cooking, vessel may be mounted directly on the water heater, and it'is to be underspirit of the invention; all such I aim to include in the scope of theappended claims. What I claim as new and desire to secure by Letters Patent is:

1. A heating system, including an annular water heater for use with gas ranges, gas heaters and the like, the inner and outer walls of the heater being substantially vertical, an annular gas vburner arranged wholly within the water heater and adapted to project the flame against the inner wall of the water heater, and a second annular gas burner arranged substantially directly beneath the annular bottom wall of the wat'cr heater,

2. A heating system, including an annular water heater for use with gas ranges, gas

heaters and the like, the-inner and outer walls of the heater being-substantially vertical, an annular gas burner arranged wholly within the annular water heater and adapted to project the flameagainst the inner wall of the water heater, a second annular gas burner arranged substantially directlybeneath the annular bottom wall of the water heater, separate means for controlling the two burners, and water circua lating pipes connected with the upper and lower portions of the water heater.

3. A heating system,'including an annular water heater adaptedto support a cooking vessel, the inner and outer walls of the heater being substantially vertical, an an nular gas burner arranged wholly within the annular water heater and adapted to project the flame against the inner wall of the water heater, a second annular gas burner arranged substantially directly beneath the annular bottom wall of the water heater, separate means for controlling the two burners, a water tank,'-a pipe leading from the lower portion of the tank to the lower portion of the water heater, and a pipe leading from the. upper portion of the water heater to the upper portion of the tank.
